Video operation effect of drum type wood chipper

What is the working principle of a drum chipper?

The wood is fed into the feed port and when it comes into contact with the cutting blade, it follows the high-speed rotation of the cutting disc for cutting. The cutting mechanism is a rotating drum with several flying knives installed on it. When the flying knives rotate, the wood is processed into wood chips. There are multiple square through-holes on the outer edge of the drum, and the qualified cut pieces fall through the mesh sieve holes and are discharged at the bottom. The larger pieces will be cut again in the machine.

Performance characteristics of wood chipper

The drum chipper is composed of the body, cutter rollers, upper and lower feeding mechanisms, hydraulic system, feeding device, and other parts.
Machine body: Made of high-strength steel plates welded together, it serves as the supporting foundation for the entire machine.
Knife roller: Two or three or four flying knives are installed on the knife stick, and the flying knives are fixed on the knife roller using specially manufactured flying knife bolts and pressure blocks.
Hydraulic system: supplied by an oil pump to the oil cylinder, the cover can be activated for easy replacement of the blades; During maintenance, the upper feeding roller assembly can be lifted to facilitate the adjustment of the gap between the flying knife and bottom knife, as well as the disassembly and assembly of the comb plate.
Upper and lower feeding mechanism: composed of feeding interface, upper and lower feeding rollers, and feeding gap adjustment mechanism. The wood entering from the feeding interface is pressed by the upper and lower feeding rollers and fed into the cutting mechanism at a certain speed to control the size of the cut wood chips; When processing thick wood, it is adjusted by the feeding gap adjustment mechanism.

The application scope of wood chipper

Suitable for a wide range of industries, such as mechanical charcoal factories, artificial board factories, biological granulation, papermaking, sawdust production, feed processing, breeding farms, mushroom cultivation bases, landscaping, etc., it is an ideal wood chip processing equipment for a large number of users.

Maintenance and upkeep of wood crusher

1. The bearings of the host bear all the load of the machine, so good lubrication has a great impact on the bearing life, which directly affects the service life and operating rate of the machine. Therefore, it is required that the injected lubricating oil be clean and sealed well.
2. Each fastening screw is prone to loosening and must be checked regularly. If there is any looseness, it should be tightened in a timely manner
3. Pay attention to checking the wear level of easily worn parts and promptly replace worn parts.
4. Regularly add lubricating oil to the friction position to ensure mechanical performance and lifespan.
5. If the bearing oil temperature rises, it should be stopped immediately to check the cause and eliminate it,
6. If there is any impact sound during the operation of the rotating gear, it should be immediately stopped for inspection and eliminated
7. After the machinery is not in use, it should be placed indoors and the sawdust inside the machinery should be cleaned to avoid affecting future use and production.

How to choose a wood chipper?

When choosing a drum chipper, the first thing to consider is the power of the equipment and the spindle speed, which directly affect the cutting efficiency and quality of the equipment. Secondly, attention should be paid to the feeding method and feeding speed of the equipment. It is necessary to choose the appropriate model based on the hardness and size of your material. In addition, the convenience of operation, maintenance, and safety protection devices of the equipment are also factors that need to be considered when purchasing.
